چکیده
It is shown in the work that plastic flow solids develops always localized manner. A macroscopic scale ~ 10-2 m characterizes localization. The zones form pattern of strain, which projection autowave processes flow, developing volume, on observed surface tested specimen. One can observe with help speckle-photography method. investigations various materials allowed to establish deformation information source for a kinetics processes. general characteristic elastic-plastic invariant couples typical characteristics autowaves same elastic waves crystal lattice. quantity ratio defined nearly forty (BCC, FCC, HCP metals and alloys, alkali-halide crystals, ceramics, rocks) studied conditions active elongation compression at temperature range 143-420 K. physical considerations are presented explain origination its relation other lattice, particular, Debye temperature. In light these considerations, it possible meaning origin invariant, derive numerous consequences from them. fact, set comprehend all regularities developed allows consider as master equation this day approach theory deformation.

Elastic-Plastic Invariant of Localized Deformation Autowaves
The parameters of localization patterns emerging at the linear stage of work hardening are discussed in the frame of autowave concept. The stress-strain diagrams have been plotted for the test samples of metals exposed to active loading. It is found that the product of phase autowave velocity and length has the same order of magnitude as the product of elastic wave rate and the lattice constant...

متن کاملElastic/plastic Buckling Analysis of Skew Thin Plates based on Incremental and Deformation Theories of Plasticity using Generalized Differential Quadrature Method
Abstract In this study, generalized differential quadrature analysis of elastic/plastic buckling of skew thin plates is presented. The governing equations are derived for the first time based on the incremental and deformation theories of plasticity and classical plate theory (CPT). The elastic/plastic behavior of plates is described by the Ramberg-Osgood model. The ranges of plate geometries...
متن کاملShort-term plasticity turns plastic
Short-term plasticity (STP) is a use-dependent change in synaptic strength on the timescale of millisecond to seconds and is observed in almost every synapse of the central nervous system. Each type of synapse has its own ‘personality‘ with respect to this property. When stimulated a few times within a second, some synapses show facilitation, others depression or else complex sequences of facil...
